Thelander’s “Photoetched Rail Yard Exposition”

By Shawna Cory

Welder Eric Thelander’s dedicated experimentation resulted in his development of a photo-etching technique combining technology from screen-printing and intaglio print-making. The process involves etching a photograph into galvanized sheet metal, and then plating it with copper. The resulting sheet of metal—and its photographically detailed relief—is virtually indestructible.
